Zenni can be earned by working a job.This will earn you 100 zenni per day you choose to do it.

Many quests will also have Zenni as a reward, see individual quests for details.

Conquering/Guarding planets is the best way to earn Zenni. Once a planet is under your control, you may choose to gather resources on it, earning you 1000 Zenni per day. Conquering/Guarding planets and defending them has its own dangers however, as shown in the planets section. Planets will also passively generate Zenni, 100 Zenni per day. So you can choose to spend time gathering money for larger profit, or do something else and gain money anyway

When defeating another player in combat, you may choose to plunder up to 30% of his total Zenni
